2nd DNF in a row! What to do? update!!

Hey Guys!! I need a clue here, today was the 2nd race in a row that I dnf due to bike problems, last week one of my radiator hose completely blew in half, so I babied the bike back to the truck, when I got there, pulled the clutch and my clutch line was gone, it broke right at the slave cylinder
Got the bike running again, decided to install the rekluse pro in it, got everything back together, rode for 15 min in my yard, everything seemed ok despite the notchiness when shifting, I figured it was normal.
Of to the race!! Drove 3hr to get there, everything looks good, I'm 3rd of the line at the start, about a mile in the bike just sputters and dies 6minutes later I get'er to fire again, off I go, about 1/2 mile she dies again, and again, decided to trhow the towell and head back to the truck, on my way back she ran ok didn't die again. I got home and washed her, and she started right up, but as soon as I went up and down the street the samething happened!
Before I take it apart again, does anybody have a clue of what this may be?? Could it be the clutch? I just don't know where to look!!
Could it be a dirty carb? Eletrical?
I love this bike but if dnfing races due to mechanical prblems starts to become a trend, I may have to look elsewhere.
Sorry for the long post, I had to get out of my system!!
Thae bike is an 08 txc450
Thanks for the help!!!
Dan.

Help us out. Tell us what bike you're riding.

What bike do you have?

sorry guys, 08 txc450

Sorry about your problems.

I too have had a few dnf's on the Husky.

1) Clutch slave issues. IMO its the weak link for racing. Replace clutch slave O ring with an X ring. There are now aftermarket clutch slaves, but i havent tried one.

The mineral oil must be the exact right amount. Too much and it will expand when hot and blow out. To little and it sucks air when on an angle...been there many time.



2) Rekluse, i cant answer, but ive not heard of it affecting the running of the motor.

3) Periodic shut off like you are expereinceing is not a common or known type Husky issue. I am guessing you have something particular to your bike, and it could be one of many many things.

Start with cleaning out your carb? It could be anything from a kinked fuel tank vent hose to a spark plug with a gap issue to a shorting stator covered in metal flake/oil paste....

Let us know what you find.

take your kill switch apart. you might find mud and water in there. it could be making a contact and cause your kill problems. easy to check and free.

keep the sugestions coming guys, I'll make a list of everything I need to go tru!

thanks
Dan.

Sorry to hear about your bad luck

I have heard that a blocked gas cap vent hose will cause those symptoms.

Good luck and let us know what the problem was.

It does sound like the symptoms of a blocked gas cap vent. Next time it happens, open the gas cap, you may just here a vacuum sucking sound

Alright guys, I started to take her apart and go trhu everything, I know this sounds stupid and sorry for my lack of knowledge, but I took the ignition cover out and a lot of oil came out? Is that normal? I ask because I think I put too much oil in it by accident before this happened, Is too much oil bad? Assuming oil IS supposed to go tru there, I look at the stator and EVEN though I don't know how to tell if a stator is good or bad, it looks in good shape, it seems like there's one piece where there isn't copper wire wounded to be a little deformed (melted) but very minor.
I took all the elec. connection apart and they had dirt in them but looked ok.
The gas cap vent hose wasn't plugged or kinked
I'm in the process of taking the carb out.
I'm chasing a ghost it seems like!
It's funny that the bike will start normally, run for a minute or two and DIES!

Thanks for the help!!
Dan.

Normal. We have wet stators.

You have three things to chase Spark, Fuel and Air.
When it won't start check the spark first.
Then you will know where to move next.
Save your self a lot of extra work and go one step at a time.

Right, It has spark, It starts just like normal
I haven't checked fuel, that's my next step.
What boggles my mind is the fact that she runs absolutely fine for a min and shuts off!!!

Well then I would start at the tank vent and work my way to the carb.
Vent, petcock, fuel lines and then look at disassembling the carb. Then same in the carb, float, needle, jets, ports.

i had the same thing happen to my tc 250, i blew the t fitting and it shut off a few miles later when i was trying to limp it back to the truck, didnt think anything of it, replaced the fitting with a y fitting and went to ride it, as soon as it got hot it would shut off and i would kick for minutes before it started again, come to find out when it blew the hose it was soo hot that the oil got too hot and it cooked one of the poles on the stator causing it to short out only after it heats up, when i got the new one it was very obvious that it was bad with the discoloring of the stator

on another note ive had two stators go bad in my 08 txc 250s with less than 15 hours on them, one wasnt soldiered correctly and the other just fell apart, literally

Ok. here's an update!!! I took the carb apart and everything looked good, here are some pics of the stator

[/IMG]Tell me what you guys think!!!

Thanks
Dan.

OK.

1) Stator is wet as pointed out, and thats good, means there is more oil in the motor. ANyway--its surrounded by a huge magnet, your flywheel. The magent grabs little bits of normal wear metal 'paste' - little particles in oil, when enough build up, it forms a metal paste 'bridge' to the stator, and shorts it. It usually is black and white, meaning it just dies for good, but it can 'slowly' go out-but its not common. Look for the metal paste on the underside of where the stator would rest, and clean it out. Do this every 1000 miles.

2) It really sounds more like a gasoline issue. Bike runs for 1 minute and dies. Thats about how much gas in in a carb, a minutes worth.

Check for sticking inlet valve, blocked jets (blow thru them and look thru then at the sun--you can see the dirt..., properly installed slide (the FCR type carb can run with a slide in backwards, and it runs horribly!) and the whole flow of the fuel from the tank, etc.

At least thats what i would focus on right now.

If you think its hard getting that carb off......you've never owned a modern aluminum framed bike like a Honda!
The Husky carb is the easiest to take off of all new dirt bikes. Just sayin.

Keep at it, we are here, and we WILL figure this out and get you riding again.

PS--was the spark plug gap ok when you took it out? Was the plug wet?

Hey guys The same problem happened today at the race!! During the week, I took the bike apart, inspected the carb, checked the valves, checked all the wirings, replaced the stator (THANK YOU KELLY!!!) and went for a ride saturday, rode hard for about an 1h20m and the bike ran perfect, I was very happy to say the least. Gave the bike a quick wash, got her ready for today's race, well, got my self at the line, another very good start about 1mile into the race, TOTALLY out of the blue with no warning sign she died on me again !! Tried starting for 10+ min, with the button, kicking it, nothing.
As the quad was towing me out of the course, I tried kicking it again just for kicks and guess waht happens?? it fuc@@#$ing starts so I rode back to truck and home I went with yet another DNF!! I don't know what else to do besides taking it to shop and see if their guess work is any better then mine (ours) . My championship chances are gone and so is my confidence on this bike!!
Thanks.
Dan

Isnt this why we spend the dollars and get bikes with 2 years warranty? I would be expecting some support if not a full fix from the shop.

Next time it happens check the spark as soon as it stops (while its not starting) so you can eliminate intermittent spark issue. On our 08 TE450 the spark plug lead came out of the boot that goes on the spark plug a bit and it would go utill i shoved it back in.

I think i pulled on it once and wrecked it, shoved back in and taped works fine now

Dan any chance the bike is overheating/ running hot when this is happening? I only ask because I know are race conditions here are usually much tighter and worse than we practice in. I know you said this started when you blew a rad hose, are you still running the plastic Y, is it damaged/ melted? Anyone know is the impeller on these is plastic or aluminum? I don't know how much I can help you (wrist is still busted), but I have a practice loop a few miles away that is very NETRA like. If your bike is cutting out from running hot, we would see it here. Tim

bummer ... that was a nice track. That was my first race on my cr 125. I saw a couple of husky's around the parking area. What class do you run in dan. I ran in the morning, c senior, we had the biggest line there ... 28 forty year olds still trying to get it done!!
